I had a short-lived episode where one of my customers was spamming. I was able to shut it down quickly, but not quick enough to avoid getting SMTP blacklisted by RCN. The response from their mail servers is:
SMTP error from remote mail server after initial connection:
host mx.lnh.mail.rcn.net [207.172.157.50]: 554 mx05.lnh.mail.rcn.net
No information there on what blacklist system they use, or how to get de-listed. Nothing that I can find on RCN's web site. Mail to postmaster is ignored. Mail to support is ignored. Can't get past 1st-level support over the phone. I'm stuck. Blacklisted and can't get off.
This just happened to my server about a week ago. Folks complaining they cannot get their signup emails etc, me not getting server notifications etc etc. Sure enough, showing up on a blacklist, one that checks the /24 block. So I am penalized for somebody else in block spamming.
I tried to setup godaddy email on the server, it works but not for internal emails FROM server (ie using php script to notify somebody or me). I added the mx records to the WHM and it does not work, I tried to add site to /etc/remotedomains and remove from the remotedomains but that does not work.
somebody mentioned using pears SMTP mail method, but then would have to change all the code, ugh. how can I change the main servers relay so ALLLLL email will be relayed through the godaddy servers instead of the default it is using. i am running Exim.
I have an issue with o2 - some of their mailservers have blacklisted IPs and hence mail doesn't get delivered to recipients whose ISPs subscribe to the specific blacklists.
Questions:
1 If mail is not delivered, will I ALWAYS know about it?
I've had bounce notifications from one specific ISP, but I'm wondering whether in other cases the mail will just not get through and I'll not know about it.
2 I'm aware of problems with two specific o2 IPs: 82.132.130.151 82.132.130.169
I have exim mailserver (cpanel based),and when i send mails to some domains i have got the following error
550 Service unavailable; Client host [xxx.xxx.xxx.xxx] blocked using 88.blacklist.zap; Mail From IP Banned To request removal from this list please forward this message to delist@frontbridge.com
How can i solve this issue ? How can i avoid my IP from listing in 88.blacklist.zap?
We've had a couple cases of fraud recently, and have blacklisted the IPs (which turned out to be proxy servers) of the perpetrators. It got me thinking... has anybody put together any kind of IP blacklist for fraudulent orders? Something like a DNSBL for spam, but focused on IPs that fraudsters use?
There are some companies whose reviews are mostly bad, and its not just one but many.
Some examples :
- SurfSpeedy - BuyAVPS
It should steer new users from these companies as it will leave them negative impressions of an otherwise good sector of the hosting market. Of course, these should be backed up by evidence.
I can only assume that I have a virus or adware on my server but Acunett says that there is nothing. I double checked all of my email sending php scripts and all of them are secure and not sending any spam. However in my mail queue in WHM I see spam emails and my server's IP keeps getting relisted on the blacklist located at:
[url]
AM I THE ONLY PERSON IN THE WORLD WITH THIS PROBLEM? This is getting frustrating I have probably spent over 200 hours trying to get this resolved but it seems like no one knows what to do. This is hurting my business since I have tons of emails stacked in my queue and being blocked by email providers due to that blacklist. I remove my server's IP successfully and the next day it is blacklisted again. If anything how can I check my linux server for viruses?
I am a reseller for SkyNetHosting.Net for about 3 months now and yes we are new in hosting business. For this pass 2 months I'm having issues with my host server firewall. Every time I get myself blacklist I have to summit a ticket asking for my IP to be whitelist. Its fine with me but I don't think my clients are happy with this as we are getting almost 90% non-renewal rate..
They keep saying its my fault.. Ok, I can take that.. But how do I explain to my clients and most importantly my client's visitors??
Is there anything on the firewall settings that they should tweak to minimize this?
I never had any problem when I was at hostgator...
My user experience with you guys so far has been excellent, especially the support department and if I were to single out your tech support employee, it has to be Nathan. Thumbs up for his fast and reliable support.
However I have one major complain.. And that is your firewall issue as I keeps getting block/blacklist even for a mere moment of connecting to Luna Server for less than 10sec. Yes, you heard me.. just 10sec after i login to the internet and browse my sites there is a high possibility of my IP getting blacklist.
We're not a pure web hosting company, we received more web design projects where by they also host their website on our server. So you see, we maintain most of our clients website and regular FTP to multiple websites are required.
Here are the list of things I would do 1st thing when I login to internet, including my employee and my business partner. So if we multiply the below by 4 .. We will get blacklist for sure, most of the times!!
1. Login WHMCS 2. Login Livezilla Chat Support 3. Login webmail to check emails 4. FTP Updates on clients sites
I hope you guys can re-look into the firewall sensitivity settings where by it reduce or better still does not effect us business wise.

Hello,
I recommend to change ALL your FTP/cPanel passwords at once and if you are saving them on browser, FTP clients not to do it anymore. If possible try to login from a deferent clean laptop/PC and see if you get the same problem.
Customers who save their FTP login credentials in FTP softwares like FileZilla, Cute-FTP, WS_FTP-Pro, Dreamweaver or Frontpage are prone to malicious scripts injections from their PC's using their legit cPanel login details via FTP and the owner of the domain/account were not even aware of it. Your login credentials are leaked to the hackers once a Trojan or Virus gets installed on your Windows Machine.
The easiest way to save your login credentials would be, to save them in a text document without saving the Domain name or Login Host information in the same document. To be absolutely sure your FTP account won’t get compromised, we highly recommend you choose a strong password which contains a combination of upper and lower case letters, numbers and special characters such as $?£;: while adding a new FTP login name from your cpanel control panel. If you manage multiple websites may not like this change, but losing your data and then losing your rankings in Search Engines will create more trouble.
Honestly I don't think this issue can be resolve on the user end as we are currently facing a monthly non-renewal rate of 90% from our clients. If this goes on we would end up losing our reputation and most importantly our business.
Yes, I can tell them the same message that your tech support replied to me. But my clients do not understand and they would rather find a host that are less complicated "firewall sensitive". Is there somehow you can recalibrate the firewall sensitivity, so we all can have our peace?

Hi Chester.
My Cpanel username is 'justin'.
This is with regards to my problem with the IP whitelist.
I need a no-nonsense answer.
I have visitors from the US complaining that they cannot view my site.
I cannot possibly be whitelisting everyone.
So, is it possible to tweak the filtering/firewall settings?
If it is not possible, I would like to exercise my money-back guarantee and close my account.
I would like a day to download my files and databases if that is possible.
I'd like to keep an IP blacklist, and have Apache enforce it. Because I want it to apply server-wide, I want to use it in httpd.conf, not .htaccess.
Rather than constantly editing httpd.conf by hand, I'd like to keep a file of IPs, and have Apache read that file and use it as the argument for a "deny from..." directive. Try as I might, I cannot find any documentation, nor any examples, of this usage. Is this something that's possible?
(It turns out that Apache doesn't honor /etc/hosts.deny, hence this question.)
Wondering if anyone knows of an email DNSBL that are have a real time reporting tool which directly feeds the DNSBL?
I have been using Spamcop for reporting in hopes I might be able to get some IP's listed. However so far I have not seen any IP's listed until many hours or days after they are reported (possibly going through a validation process?).
Wondering if anyone knows a more pro-active DNSBL that is fed directly by reporting and administrators?
A Wordpress install on one of my domains was compromised a few months ago, and there was a 4-hour window in which the site contained an iframe injection that lead to a malware site.
The problem was corrected, and Google stopped flagging the site as malicious within a few hours after the fix. However, every once in a while I still hear of people having problems accessing the site, all of them I think from within large corporate networks.
Are there a few common list providers that these corporate networks are likely to be subscribing to? Is there a way I can submit the domain for reevaluation? If not, how long would you think a domain would have to be clean in order to repair its reputation on these lists?
What scripts/tools or configurations on a CPanel/WHM (Centos) server can you make to prevent spam from getting sent out by "clients" you may be hosting or just spam in general.
As, in the hosting industry, you are always going to have a client or two successfully send out spam, as some spam may not look like spam, but if you do not follow all the guildlines, I know regular newsletters can be consider spam.
I set multiple mail servers (eg media-26.com) in the black list of server-wide mail settings but i still get spams from these mail servers..does it work properly?
Almost all mail adresses on my server is getting a spam mail from same mail marketing company everyday and i want to block them... Normally i just add the mail address to blacklist from "Spam Filter Settings" but this company is opening new addresses everyday and it is impossible to add all of them to blacklist so i need adding it as a regex to the blacklist...
The company i am talking about is opening mail addresses every day like below...
As you can see all mail addresses begin with "nrt"+"6 digits of day"+"free mail provider", so right now i am using the regex below and it is already added to the blacklist but they are still able to send me... What can i do now?
